AKG K550 II Closed Over-Ears for $90 (ships April)

In addition to the AKG K553 going for $120 at Massdrop, there’s another sale in this series, the closed-back over-ear AKG K550 Mark II is offered for $90 with free shipping at the official Harman Audio store. I don’t recall what the difference is between the Mark II versus the original. NOTE however that the shipping estimate for this is April 2017, so don’t buy it if you want/need it to get there quickly.
